The curl development team has announced the release of curl 8.15.0, marking the 269th official release of the popular command-line tool and library.
This latest version delivers significant improvements with 233 documented bugfixes and 334 commits, representing a substantial maintenance update that addresses numerous issues reported by the community.
The release follows a shorter development cycle of 42 days, bringing the total project timeline to 9,980 days since its inception.
The most significant change in curl 8.15.0 involves the removal of support for two SSL/TLS backends: Secure Transport and BearSSL.
This decision represents a strategic shift in the project’s approach to SSL/TLS implementation, potentially affecting users who relied on these specific cryptographic backends for their applications.
Secure Transport, Apple native SSL/TLS implementation, and BearSSL, a lightweight SSL library, are no longer supported options for curl’s SSL/TLS operations.
This removal may require users currently utilizing these backends to migrate to alternative SSL/TLS implementations such as OpenSSL, GnuTLS, or other supported libraries.
The development team’s decision to discontinue support for these backends likely stems from maintenance considerations and the need to focus resources on more widely adopted SSL/TLS solutions.
Users should review their current configurations and update their systems accordingly to ensure continued functionality.
Development Activity
The development metrics for curl 8.15.0 demonstrate the project’s continued vitality and active maintenance. Key statistics for this release include:
